which broker trades on weekends?

Brokers who offer cryptocurrency CFDs will allow you trade it during weekends but you cannot trade currency pairs over the weekend.

Several brokers offer cryptocurrency so you can check their product catalogue to see which has the lowest spread.

As for weekend withdrawals, I think Exness allows weenend withdrawals.

Deriv; you can trade synthetic indices with them on weekends

These brokers allow crypto trading 24/7, including Saturday and Sunday — because cryptocurrency markets operate all week:

Exness

Withdrawal processing depends on the method and region — crypto/e-wallet methods are usually swifter.

Withdrawals may be requested on weekends — payout timing varies by method (crypto tends to be quicker).
